MUSIC-LEAF TURNER.

Specification of Letters Patent.

Patented Nov. '7, 1905.

Application filed May 24, 1904. Serial No- 209,454.

To (11 whom, it may concern:

Be it known that I, GEORGE SYMoNs BUDGE, a subject of the King of GreatBritain, residing at Devonport, Auckland, in the Colony of New Zealand,have invented a new and useful Improved Music-Leaf Turner; and I dohereby declare the following to be a full, clear, and exact descriptionof the same.

This invention relates to means whereby the leaves of music may beautomatically turned over. The means devised are such that any of theleaves may be turned back by hand, so as to allow of any portion of themusic being repeated and then again released, so as to be automaticallyturned over without interfering ivith the order of turning of the otherleaves.

The appliances employed in carrying out the inventions purpose consistof a number of arms loosely mounted one above the other upon a commonspindle secured within a frame. The free ends of these arms are providedwith clips by means of which the sheets of music may be attachedthereto. The arms are connected to springs the tendency of which is tokeep them normally turned over to the left. Catches are provided to theright of the arm-spindle, by means of which the arms may be held. Meansare provided wherebythe arms may be released and their springs allowedto draw them and the sheets to which they have been attached over one byone, as desired by the player. In order, however, that the invention maybe properly understood, reference will he made to the accompanying sheetof drawings, in which Figure 1 is a front elevation of the whole of theappliance. Fig. 2 is a detail elevation, on an enlarged scale. of thearms at their pivoted ends and the means for retaining and releasingthem. Fig. 3is a plan view of Fig. 2. Fig. 4: is a sectional plan takenon the line 1 2 of Fig. 2. Fig. 5 is a front elevation of the mechanismthat is used for operating the releasing means. Fig. 6 is a plan of thesame.

a is a base-plate to which the various appliances are attached and whichis adapted to be fixed to the music-rest of pianofortes in such a manneras to allow of the music-sheets resting near its top edge. Secured nearthe cen ter of the base-board (Z is a frame 6, that carries a verticalspindle 0. Upon this spindle are loosely mounted the arms (Z, the bossof each of which is provided with a short inward extension-piece a, (seeFig. 4,) to which one end of a helical spring f is secured, the otherend of such spring being fastened to the back of the frame Z). The freeends of the arms (Z extend horizontally along the base-board and aremade of such a length that each one shall project beyond the end of theone immediately above it. To the extremities of each one is secured aspring-clip g, so designed as to be adapted to grip tightly upon thebottom edge of a music sheet placed within it. These clips are sodisposed that they shall lie in a row alongside each other, in themanner shown in Fig. 1.

The tendency of the springs f is to keep the arms (Z normally drawn overto the lefthand position shown in the drawings, so that by attaching asheet to one of the arms and turning such arm upon the spindle 0 acrossto the other side and then releasing it the arm and the sheet to whichit is attached will be turned back to the normal position by the tensionof the spring f.

Secured within the frame I) on the right-hand side of thespindle c isanother vertical spindle 7L. Upon this spindle are loosely mounted anumber of lever catches 1'. These catches correspond in number with thatof the arms (Z and are each formed with an outwardly-extending portion7a, the extremity of which is formed with a tooth adapted to engage witha small pin Z, projecting upward from the arm (Z. The levers fare alsoprovided with ex tension-pieces m, that extend along against the face ofthe frame 7). Secured upon the face of this frame are a number of fiatsprings or, the ends of which bear outward against the under sides ofthe extension-pieces m and tend to keep the extension-pieces Zr:normally turned inward. When the arms (Z are thus turned across to theright-hand position, the pins Z will engage against the top of thecorresponding extension-pieces Zn, will push such slightly aside, sothat they may pass behind the teeth, and will then be caught by suchteeth and the arms held from turning back.

The appliances employed for releasing the arms from engagement with thecatches consist of a vertical spindle 0, mounted in the frame above theextension-pieces m. This spindle is formed with a number of pallets pprojecting from its face, such pallets being adapted to engage with anddepress the extension-pieces m as the spindle is revolved. The number ofpallets correspond to the number of catches and the number of arms used,and they are so arranged in relation to each other that they will engagewith each of the extensions m in turn as the spindle is revolved througha full revolution. beginning with the top ones and ending with thebottom one. I/Vhen the extension-pieces m are thus depressed, theextensions Z; will be turned out of engagement with the pins Z of thearms (Z, so that such arms will be free to be turned across to thenormal position.

Upon the top end. of the spindle 0 is secured a ratchet-wheel 1', (seeFig. 3,) the number of teeth in which correspond also to the number ofarms (Z. Engaging with the teeth of this ratchet-wheel 1' is a pawl s,that is connected to the end of a rod 2, extending in suitable guidesalong the face of the base a. The pawl is kept in engagement with theratchet-wheel by means of a spring w, bearing against the outer face ofthe rod 6.

Pivoted against the face of the base a near its left-hand end is abell-crank lever a), (see Figs. 5 and 6,) one arm of which is connectedto the rod 2/, while the other arm is hinged to the top of aloosely-hung lever-plate w. This plate is provided with a rest on eachof its sides, in which rest arms and 1 that are hinged at their innerends to the base 0. These arms extend outward and are each provided withfinger-pieces on their free ends. By depressing the arm 1/ the plate n;will be pulled down and will turn the bell-crank lever 0, so that alongitudinal motion will be given the rod t, causing its pawl to engagewith and partially revolve the ratchet o" and spindle 0. \Vhen thepressure is released, the spring 3, secured to the rod 6', and the basea will draw back the rod to its normal position, so that the pawl shallslip over and engage with the next tooth in the ratchet-wheel.

Should it be desired to repeat the music on any of the pages, to turnsuch page the arm or is depressed. This will only give enough movementto the rod 5 to turn the pallet 19 on the spindle 0 enough to releasethe desired arm (Z. IV hen the rod 6 is thus drawn back by the spring 3,its pawl shall not be given enough movement to slip over the next toothof the ratchet-wheel. Thus the arm released may be turned back again tobe caught by its catch and may then be again released by pressing uponthe arm ;2 in the manner before described. The remaining leaves of themusic may then be turned in their proper order.

To the bottom end of the spindle 0 is secured a small cylinder 4, theperipheral face of which is marked with numerals corresponding to thepositions of the pallets p. This cylinder is mounted within a recessformed in the frame 6 and the front of which 18 opened enough to showeach numeral on the cylinder. The number of the sheet turned may thus beindicated.

\Vhat I claim as my invention, and desire to secure by Letters Patent,is

1. In music-leaf turners, a vertical baseplate, a vertical spindlemounted in front thereof, a number of arms loosely pivoted one above theother on such spindle, spring-clips on the free ends of such arms,springs connected to the arms so as to keep them normally turned over toone side, catches mounted upon a vertical rod upon the other side of thespindle and formed with outwardly-extending tooth portions adapted toengage with and retain the arms when turned across, and with tailextensions, springs between the face of the base-plate and theextensions and pressing such outward, a vertical spindle mounted infront of the extensions and formed with pallet projections upon it,which, as the spindle is rotated, are adapted to engage with and pressupon the tail extensions of the catches in turn, and means whereby suchspindle may be intermittently rotated, and for varying the degree ofmovement thereof, substantially as specified.

2. In music-leaf turners, a vertical baseplate, a vertical spindlemounted in front thereof, a number of arms loosely pivoted one above theother on such spindle, spring-clips on the free ends of such arms,springs connected to the arms so as to keep them normally turned over toone side, catches mounted upon a vertical rod upon the other side of thespindle and formed with outwardly-extending tooth portions, and withtail extensions, a vcrtical spindle mounted adjacent the extensions andformed with pallet projections upon it, a ratchet-wheel secured upon thetop of the pallet-spindle, a sliding rod extending longitudinally alongthe base-plate, a pawl on the end of the sliding rod engaging with theteeth of the ratchet-wheel, a bell-crank lever pivoted to the base-plateone arm of which is connected to the sliding rod, a hanging platesuspended from the other arm of the bellcrank lever, depressions formedon each edge of the hanging plate and linger-pieces hinged to thebase-plate and resting in each depression, said fi nger-pieees givingthe rod different degrees of movement, substantially as hereinspecified.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
